Abstract
A shift range control apparatus controls driving of a motor in a shift range switching system provided with the motor and a shift range switching mechanism. A drive controller controls the driving of the motor to fit an engaging member in a recess according to a shift range in response to that the shift range is switched. A polarity determination device determines a polarity of a stator, which faces a rotor. The drive controller causes the engaging member to move to the recess according to the shift range, and then performs cancel energization control to energize a coil with a cancellation current which is a current reducing the magnetic flux density of the stator according to the polarity of the stator.
